Question

    Ifthediameterofacapillaryisdoubled, then the rise of

    water in it will be –
    A two times Correct Answer Incorrect Answer
    B half Correct Answer Incorrect Answer
    C four times Correct Answer Incorrect Answer
    D no change Correct Answer Incorrect Answer

    Solution

    Radius of a capillary tube is inverselyproportionaltotheheightoftheliquid column.So,if radiusofthetubeisdoubled, rise of level of water will becomes half of the previous rise in capillary tube. Capillary action, or capillarity, is the abilityof a liquid to flowin narrow spaces without the assistance of, and in opposition to external forces like gravity.
